Carmelo Anthony and La La Vazquez have expanded their apartment search to the Upper West Side. Sources have spotted Vazquez checking out a three-bedroom, three-bath, 1,700- square-foot unit at The Rushmore since she and her Knicks hubby arrived from Denver. According to streeteasy.com, the two-floor pad with a spectacular Hudson River view rents for $10,800 a month. The building is also home to Robin Williams, and Alex Rodriguez just signed a deal to buy a $6 million penthouse there.
